Application filed Mlmh zs, 1889.

T all whom zit may concern;

Be itknown that I, CHARLES VICTOR ROTE,

a cil:izen 0f t-he Unitecl Stat6s, ancl a resident of Lancaster, eounty 0f Lancaster, ancl State 01: Pennsylvania, l1ave invenfiecl a new and; .nseful Improvementin Oar-Brakes, 0f wh ieh the following is a full, elear, ancl exact (leseription, referenee being had to ehe accompanying drawings, making part 0f this sp'eci fication.

My invention relates t0 means f0r giving. inereasecl foree to alle. application 0f vehiclebrakes; anc l it co nsists in the eombinat-ion, with tl1e brake-shoes,of a novel arrangement 0f levers and conneetioi1s whereby the frietion of alle wheels upon the brake-shoeswhen 13l1e latter a1e brought into aetion, is util'izecl for applying tl1e brakes With greatly-inereased foree, as hereinafter deseribecl ancl elaimecl. In the aceornpanying drawings'Figure l is a plan 01 top view 0f a ear't-ruek With my improvemenus applieclu Fig. 2 is a sicle elemtion 0f tl1e sarne, partly in se eti en, to show ehe arrangement 0f son1e 0f the parts." Fig. 3 is a transverse seetion through alle sills ab one side 0f tl1e truck, sl1owing 011e 0f the brake-sl1oes ancl the rock-shaft and its 0011- neetions With said shoe f01 operating bhe same in side elevation; and Figs: 4 and 5 are cletail views showing modifieations in the forxn 0f the lever attaehecl 110 tl1e brake-shoes f01" operating the Same.

A and A indieate longitudinal frame bars 01' sills 0f the truek-franne, two 01 more of Wl1ich are employedat eaeh side 0f tl1e frame- A A indieating the outerbars 01 wheel-pieces, ancl A transverse conneeting-bars, and B B tl1e carrying-wheels. The truek rnay be 0f any usual er preferrecl construction, anal, as 0 my improvements usecl upon bot li sicles there- 0f .are duplicates, substantially, one 0f Ehe otl1er, it Will loe necessary t0 describe those 011 one side only.

C O inclicate a divided longitudinally-arrangeclr0ck-shaft, the two parts there0f being mounted in suijsable bearing-braekets a a on one of the side bare 01 wheel-pieces, and provided ab its encls overhanging the encls of saicl side bars with short; erank-arms O C Serial N0. 305,067. (N0 model.)

frorn whieh, through suitable pendent links D, the outer brake-beams E and E and the brak'e-shoe's F an(l- F, conneeted therewith, are suspended. T0 relieve ehe crank-arms O ancl 0 of 1;l1e weigha 0f ehe brake beams and shoes when tl1e latter are not in aeti0n, C-Shaped 01 ocl1er suirable f0iln of springs Z) are employed, attaehed ab one en(l to the truek-frame and at the 0ther to the brake- 1 beams 01 t0 spu1s 01' pins 011 the links D t0 Support saicl beams ancl shoes, as shown.

Tl1e brake-shoes F and F between tl1e tr1iek-wheels are pivotally seeured to tl1e ends 0f sh0rt levers G and G", mountecl 011 sl1ort transverse sl1afts 01 pivots g g, seeurecl in snitable braekets h, attaehecl t0 ehe a(ljaeent sicles of the bare 01 sills A an(l A. Coilecl springs z 71 011 tl1e pivots g 011 opposite sides 0f the levers G ancl G serve t0 hold the latter in proper position 011 said pivots, while at the same tin1e allowing them a limited freedom of movement 01 lateral play, snffieient t0 enable them t0 aeeommodate themselves 10 any ehange in tl1e position of ehe wheel's clue t0 tl1e turning 0f eurves 0r fo 0 otheieauses. -These levers G and G and the brake- 7 5 shoes eonneered therewith are shown arranged consiclerably above the plane of the ear-wheel axles, this arrangement being n'eeessary Where the wlueels are arrangecl in elose proximity With each 0ther, as frequently happens where shorttrueks 01 m01e than two wheels 011 eaeh side tl1ereof are employed. The innex acljaeent ends of the levers G and G have chains k k conneeted so them, whiel1 extencl up over Sheaves orpulleys.l J, journaled in suioable angular braekets j, seeuredto tl1e sills A, and the nee in loop f01rn or in two parts (see Fig. 3) b0th over and under the roek-shaft O, 130 whieh the encl of said loop is seeured in such manner that the rocking 0f the shafb in eithe1 direcion Will serve to Wind the ehain upon it( and so to lift the ende of the levers G ancl G connecoed therewith.

shown, ehe usual forrn of eam-bloeks may be employed for tl1e intermecliae brakes, ancl these may be eonnectecl 00 alle ehains t0 be Instead of levers G and G of the f011n 5 drawn up thereby; 01 the form of double toggle links o1 levers shown at G in Fig. 4, the elbow 01 bell-crank form 0f lever shown at G Fig. 5, 01 other suitable form of lever, may be employed, conneeted with the brake-shoes f01' opemting them, if preferred. The ends ot' the levers to Whieh the brake blocks 0r shoes are conneoted are pmvided Wilh screwthreaded sockets, in which short screw-threaded rods f, to whieh the brake-blocks are pivoted, are seeured adjustably for adapting them t0 compensate f01' wear .0r t0 give the proper adjusument o0 the shoes, and are he1d at such adjustment by means of jam nuts The form of leve1 and the arrangement thereof first described are preferred where the car-wheels are brought close together and but little space is left to accommodate the parts,- as explained; bub it will be apparent that other forms 0f lever referred to.may be employed and that the brake-shoes and levers connecfed the rewith may be located in a lower plane, n1ore near1y approximating the plane 0f t-he car-wheel axles, where there is space enough between tl1e wheels (0 accommodate the parts.

L and L indicate the ordinary "b1akelevers, rund L a 10d eonnecting them. These may be of the ordinary consoruction and zu rangement, and the levers may be connected t0 the bmkebeams E and E and operated in any usual manner. VVhatever may be the power applied f01' operating the beams E und E, whether band 01 oherwise, it will be apparent that when the brake-shoes I and F am thrown i'nto frietional contact with the wheels the action 0f the wheels, moving in either direetion, Will be to pull downward. 011 the shoe and rock-shaft ab one end and t0 pusl1 upward ab the ot-her end, and so t0 rock the two parts of he shaft C in opposite directions, which causes the chains k k hto be wound up and wrapped upon i'm, and thereby to draw upward 011 the ends of "uhe levers G and G und so bo apply the brakes F and F with a power proportionate to the friction of Ehe wheels upon the brakes F und F, and which is found very eflective in aetion.

I-Iaving 110W deseribed my invention,l claim as new 1. The combination, with the truck-frmne, of the roek-shafu having crank arms 001gnected uo the outer brake beams 01 shoes, levers carrying intermediato brake-shoes, and ehains conneoting said levers with said rockshaft, substantially as deseribed.

2. The 1evers carrying the brake-shoes intermediate the carwheels, in combination With a, rock-shaft 0n the truek-frame, chains connecting said levers With the roek-shaft, and bra-keshoes also conneeted to said rockshaft f01 operating it and the intermediate brake levers and shoes, substantially as (10- scribed.

3. The combination, with the truck-frmne, of the divided rock-shafts extending lengthwise of said frame and provided at their 0uter ends with crank-arms,brake-shoes suspended from said arms, and intermediate shoes 0011- nected 130 and operated from said rock-shafts, substantially as deseribed.

4. 'lhe combination, witl1 the truck-frmne, of longitudinally-arranged rock-shafts hav ing crank-arms at their ends, brake-shoes suspended from said arms, springs f01 upholding said brake-shoes, and intermediate brake-shoes and their supporting-levers C011- nected t0 amd operated from said rocleshafts, substantially as described.

5. 'lhe combination,in a bmke mechanism, 0f the rock-shafts O, having crankarms C and C", brake -shoes F am]. F, supportinglinks D thexefor, interrnediate shoes F zmd F supporting-levers therefor, and chains k, connecting said levers with the rock-shafts, substantially as described.

In testi:nony whereof I have hereunto sei; my band this 25th day of March, A. D. 1889.
